Software Upgrade The chip inside the LED is designed with a FLASH ROM memory program: it can be erased and reprogrammed, it can be also updated via the US port. the program is related to the chip fucntion ---Different functions of chips need to be planted with different versions of prgrams. Please ugrade the new software by the US port the instruction steps below: Please copy the new software to the US Power O the TV and press MEU to display the main menu,then press / to the OPTIO menu. And then select the software in the root of your US memory, Press ETER.then press to update and to cancel. Remarks: When the first upgrading is finished, the action of turning on the tv will be a little slow. So when you turn on the TV at the first time, you need to press the "power" key on the remote control several times until you turn on the tv. Turning on the TV at the first time is very important, you need to operate it carefully to avoid the upgrading is not successful.
